23 Claims.

This invention relates to high-speed cigar rolling machines, and more particularly to a cigar rolling machine provided with mechanism wherein a soft work bunch machine may be detached and a fresh work bunch machine may be substituted one for the other to cooperate with said rolling machine and produce long or short filler cigars with a minimum of changes to the other mechanism.

It is an object of this machine to provide a high-speed cigar machine which operates at a much higher speed than that of existing cigar machines.

Also, since crevices and pockets on machines are difficult to clean, and encourage a dirty machine, all possible moving parts of the machine have been enclosed with a symmetry of outline and plane surfaces that are easily cleaned Experience has shown that dirt is one of the worst enemies to long wear in a machine and this is particularly true of cigar machines which handle tobacco, which may be coated with field dust and other abrasive materials. If this dust be allowed to remain in the machine it works into bearings and cams and produces rapid wear. Hence, it is a further object of the invention to provide a high-speed cigar machine in which the working parts thereof are substantially enclosed in order to protect them from dust, dirt and other extraneous materials commonly present in tobacco, which therefore results in a machine of unusual efficiency and durability from a point of view of wear and tear on its operative parts.

It is a further object of the invention to provide means for quickly effecting positive removal of waste tobacco products from adjacent tobacco cutting mechanisms of the machine, thereby making it possible for the operator to utilize more time in making cigars, and salvage these waste products in a sanitary state.

It is an additional object of the invention to provide a cigar machine and to arrange the drive thereof so that a rolling unit may be selectively attached to either a long or a short filler bunch forming device whereby either a complete long filler or short filler cigar machine results.

Another object of this invention is to provide a rolling machine with drive clutch control means, both hand and foot, at convenient points, so that when used with either a long filler bunch machine or "soft work bunch machine, they will be accessible to the bunch machine operator without change or connection. This makes it possible to use either type bunch machine with? out changing the rolling end.

The clutch of the illustrated embodiment of the invention is provided with a continuously running motor driven shaft which projects through a housing, where a coupling connects it to the drive shaft of the short filler or soft Work bunch machine. In the interior of the clutch housing a sun pinion attached to this shaft drives the gears of a planetary system which are connected to a sleeve which also projects through the housing. A coupling attached to this sleeve provides the driving means for the long filler or fresh work bunch machine, whenever it is associated with the rolling machine. The clutch, which is shown herein by way of example, has an internal expanding brake shoe working on an internal gear within which the planetary gears travel to drive the sleeve. When the brake is released, the planetary gears drive the internal gear.- The brake band is expanded by a screw and lever actuated by an electric solenoid controlled either by manual or automatic switches.

The invention also contemplates the provision of a cigar rolling machine having associated therewith: a soft work [bunch forming device wherein control means on the rolling machine are adapted to coordinate with controls on the soft work bunch forming machine.

According to the present invention a cigar rolling machine is provided with driving mechanism so constructed that by juxtaposing either a long or a short filler cigar bunch forming mechanism adjacent thereto, the working parts thereof may be joined together by means of a coupling mechanism in order that the cigar rolling machine can be operated in conjunction with either of said bunch forming mechanisms. It is, therefore, a further object of the invention to provide a cigar rolling machine with means for driving either a long filler or a short filler bunch machine in synchronism therewith and in order that all operative parts of the bunch making machine may co-ordinate with the operation of the rolling machine.

In the machine of this invention, in order to achieve the object of interchangeability, the illustrated embodiment shows a rolling machine having an electrically controlled mechanical clutch by which means the drive is transferred, from a continuously rotating solid drive shaft which is arranged to drive a soft work bunch forming machine, to a hollow shaft which is concentric with the solid shaft but which is normally stationary. By means of a suitable coupling, the drive of the hollow shaft can be transmitted to a long filler bunch forming machine. When the rolling machine is operated with a long filler cigar bunch forming machine therefore the hollow coupled shaft is driven in synchronism with the hollow driven shaft of the clutch at ,a speed depending upon the speed of said shaft and the gear ratio of the clutch whereas with respect to the operation of a short filler bunch forming machine coupling with they 1 rolling machine it is driven continuously from the motor at a different speed determined by the motor speed by the ratio of the drive pulley. The clutch is controlled by a driving ring through a solenoid which responds to a number of manual, foot and limit switches, the opening of any one of the manual switches stops the machine in any position while the limit switch stallsithe machine .at zero if the manual switches are closed; I V

When the machine operates as a fresh work machine, the foot switches cannot stop the machine, once it is started; the machine is stopped once each cycle by a limit switch. In order to restart the fresh work machine a pair of foot pedals are depressed which again close the circuit and start the machine. It is to be noted that even though the limit switch operates at the end of each cycle, the machine can be kept in continuous operation by maintaining the foot .pedals depressed. However, when the machine through proper substitution of units becomes a soft Work machine, due to the fact that there are certain points in the cycle when the hands of the operatorat the rolling station might possibly be in danger of being injured, one of the foot pedals has been arranged to stop the rolling machine in any position if any danger to the operator should arise. This arrangement also makes it possible for the bunch operator to stop the operation of the rolling machine and catch up, in the event that she has fallen behind in placing bunches in the turret pockets, Thus, one motor attached to the cigar rolling end will drive both the rolling and bunch making machines at their proper speeds andeach machine can be run independently of each .other from that motor.

Accordingly, it is a further object of the invention to provide driving mechanism which may selectively drive either a long or short filler cigar bunch forming machine, and to provide a number of switch controls which allow stoppage of the machine, in any desired position.

It is an additional object also to provide a single driving motor and selective driving means for operating a cigar bunch rolling machine in conjunction with either a long or a short filler bunch forming machine as may be desired.

In order to make it possible to later substitute either a long for a short filler bunch forming machine, or vice versa, for cooperation with the cigar rolling machine, transfer mechanism which transports bunches from the bunch forming machine to the wrapping station of an improved type, has been provided so that nochange in the transfer structure is necessary, except to change the type of gripper unit: head, whenever a substit'ution is made. This has been accomplished by so arranging the bunch rolling device of the rolling machine, and the bunch concentrators of the long and short filler bunch forming machines that the bunch transfers of the rolling machine can be used with a minimum of change as mentioned above.

This invention also consists in the provision of novel means for controlling the clutch of the cigar rolling mechanism which is responsible for the driving of either the long or the short filler bunch forming mechanism. These control means consist of a rotating member which cyclically operates an electric switch which is a part of the machine so as to interrupt the operation thereof at least once during each cycle of the machine during its operation. Additional means are also provided for maintaining the continued operation of the machine regardless of the functioning of the device which interrupts'the operation cyclically. I

Accordingly, it is a further object of the machine to provide improved control means which will maintain the operation of the machine at its most efficient rate of speed.

With these and other objects, not specifically mentioned, in view, the invention consistsof certain constructions and combinations which will be set forth more in detail in the specification and then described more fully in the claims hereinto appended.

Referring to Figs. 1 and 2, the improved cigar rolling machine consists of a bunch transfer II which picks up the finished bunches B from a bunch making machine, which may be either a long or a short filler bunch machine, as shown in Fig. 9 and Fig. 10, and carries them along the path indicated by the arrow I3 in Fig. 2 to the rolling device I4 in which a cigar wrapper cut on the die I5 by the cutting rollers I6 and brought into position by the wrapper carrier I1, guided by cams I8 and I9, is wound around the bunch. The tuck end of the wrapper is placed on the bunch by the tuck-needle 20 in the conventional manner, and its flag end, to which a dab of paste has been applied by the paster 2! on its way to the wrapping device, is expelled from the carrier by a blow-off 22, which may be of the type shown in my co-pending application, Serial No. 102,445, filed September 26, 1936, now Patent No. 2,215,490 granted September 24,

1940. A cigar transfer 23 then transports the wrapped cigar C along path 24, 1, to reroller 25 (Figs. 9 and 10) in which the wrapper is smoothed and the softened cigar, after being trimmed to size, by knives 35I and treated by knurler 352, is discharged from the cradle 25, to be collected and given a finishing touch in the hand knurler 21 by the operator.

The construction of the rolling device I4 in the embodiment herein illustrated is similar to that disclosed in co-pending application No. 107,792, filed October 2 7, 1936, by J. P. Durning, which is now Patent No. 2,290,171, granted July 21, 1942; while the wrapper carrier I1 may be of the type described in my co-pending application above referred to. The paster 2I may be similar in construction to that shown in the United States Patent No. 2,912,149, issued August 20, 1935, to 1.11. Wheeler, and, therefore, further detailed description of these mechanisms is believed unnecessary.

In the embodiment selected for illustration, the machine is driven by a motor 28 controlled by a starting switch 30 through a clutch 29 which is electrically controlled by conveniently located hand switches 3I, 32 and by foot pedal switches 33, 34 and 34', and limit switch I61, the former actuated by the operator of the rolling machine and the. latter by the operator of the bunch machine. For convenience in installing and subsequent checkup, a jogging or inching switch 35. is provided, by which the machine can'be advanced step by step through increments of a cycle, for checking on the timing, and for making other adjustments of the different parts whenever necessary.

The operating units of the machine are mounted on a base plate 38 suitably supported by side frames 31, 38 and by an end frame 39 which are completely covered by metal sheeting 40. The end frames 31, 38, support a cam shaft M and fulcrum shafts 42, 43, 44, 45, and 45, the inner ends of shafts 42 and 43 being supported in housings 41 and 43, respectively. attached to base plate 36. The end frame 38 also carries the bracket 49 on which the motor 28 is mounted. The metal sheeting which encloses the front and sides of the machine preferably is removably mounted in order, both to enhance the appearance thereof, and provide accessibility to the working parts for repairs and desired changes.

The cam shaft M has a worm wheel 50 driven by a worm 5| on a hollow shaft 52 supported in the housing 53 of wheel 53. The shaft 52 is connected by a coupling 54 of conventional design, to the hollow shaft 55 of the clutch 29, a solid shaft 53, passing through shafts 52 and 55, being coupled to a shaft 51 supported by the clutch housing 23 and carrying a pulley 58 driven by a belt 53 from the pulley I55 of the motor 28. The housing 41 is intended to carry bunch shaping turret I31 whenever the rolling machine is used in combination with a short filler or soft work bunch forming mechanism (see Fig. 911). When the machine is to be converted into a long filler or fresh work combination, the turret I31 and housing 41 are removed, and the inner end of fulcrum shaft 42 is journalled in a bearing bracket 36%] (Figure 7) hung from the machine base 35. In making this conversion, shafts 42 and 44 (Figures 7, 9a and 9b) are removed in an obvious manner and withdraw from the frame 31, 38. In the case of shaft 42, one end is withdrawn from a bearing in bracket 41. Upon removal of these shafts and screws 35L the bracket 41 and its associated operating elements for turret I31, as shown in Figures '7 and 9a, can be lifted from the machine, and bracket 3'60 substituted therefor and hung to frame 35 in any suitable known manner (Figure 9b). Shafts 42 and 44 are then replaced and the cigar rolling part of the machine is then ready to be connected to a long filler bunch making unit to make long filler cigars.

It will be seen, therefore, that the complete conversion of the machine from a short to a long filler cigar machine involves the removal of four screws 35L the disconnection of coupling 2115, Figures 9, 9a and 9b, the removal of turret I31 and the substitution of the transfer head of Fig. 12 for that of Fig, 16. All of these changes can be effected with great rapidity and dispatch without necessitating a complete reorganization of the machine and the long filler unit may be juxtaposed against the cigar rolling machine and coupled thereto in working order as shown in Fig; 10. The cigar machine shown in Figure 9 can b converted into a. long filler machine by disconnecting coupling 295 and electrical contact 2I4 whereupon the whole short fillerforming mechanism, with the exception of turret. I31,

can be moved away from the rolling end. By withdrawing shafts 42 and 44 and removing four screws 39 I, turret I31 can belifted from the rolling end of the machine, which is then ready for the long fillerbunch forming unit. The next step in the conversion is to move unit L. F. (Figure 10) adjacent th rolling end and couple shaft 245 to shaft 52 of the rolling end, thereby completing the change over.

Integral with shaft 51 are two gears BI and 62, Figs. 4 and 5, the former meshing with a gear 63 which in turn engages a gear 64, thereby driving a shaft 65 supported in housing 29. 'The shaft 51 being continuously driven by the motor 28, the shaft 65, which is geared to the hand knurler 21, will therefore, run as long as current is supplied to the motor.

The gear 62 constitutes the sun gear of a planetary system in which th intermediate gears 66, carried by a collar 61 fast on shaft 55, run on an internal gear 88, loose on a hub of housing 29, when the said internal gear is held stationary by an expansible ring 69 engaging with the same. The ring 89 is expanded and contracted by a right and left hand screw 10, Figs. 5 and 6, fitted into sockets H and turnable by an arm 12 actuated through'a rod 13 by the plunger 14 of a solenoid 15. As long as the current in the latter is on, the rod 13 is pushed towards the clutch against the pressure of a spring 16 so as to expand the ring 69, thereby driving the shaft 55; but when the current is cut off, as by opening one of the switches 3| and 32, the spring 18 returns the rod 13 to its normal position, thereby contracting the ring and releasing the internal gear 68 thus permitting the planet gears 66 to turn without driving shaft 55. The ring 69 is held in place by a pin 11 fast in clutch housing 29. The solenoid is mounted on a bracket 18 extending from clutch housing 29. A second spring 19 on rod 13, in conjunction with a slot 89 in its connecting socket 8|, serves to absorb any excess forward motion of plunger 14 after the ring ,69 is in holding engagement with gear 68. The operat ing parts of the clutch run partly in oil which is kept within the clutch by means of its casing. It will be noted in this manner that a thin film of oil will always be present between the surfaces of gear 68 and expansive ring 69 which engages the gear to effect the drive. This arrangement insures a clutch of extremely long life, and also provides a very satisfactory friction drive, which in the case of a jam in the machine will slip rather than damage the parts of the clutch.

On shaft M are mounted cams 82, 83, 84, 85, 86 and 81, (Fig. '1), also a bevel gear 88 and a spur gear 89. The gear 88 meshes with a bevel gear 99 mounted on a shaft 9| supported in pedestal 92 on base plate 39 (Fig. 1), and driving the main cam I8 of the wrapper carrier I1, the cam I8 in turn guiding the roller wheel 93 of the follower cam I9 which controls the carrier I1, as set forth in the above referred to Wheeler applicatlon.

The cam 82, by means of a follower 94 controls a lever 95 fulcrumed on shaft 44, this lever bya link 96 being connected to a rack 91, Fig. 1, which through gears 98, causes the reciprocation of a chain 99, and hence of the carrier I99 of 1 adjustable pivoted rods III and II! which are attached to the lever at one end and at their thecutting rollers I6 which is attached thereto. A sectional end elevation of the mechanismfor moving the cutting rollers I6 acrossthe wrapper die I5 is shown in Fig. 19. The rack 91 actuated by the link 96 on cam lever 95 meshes with a gear 98 loosely mounted on the hub of ascoond gear 349 mounted on a stud 336 supported by a frame 331 attached to bed plate 36. The gear 349 meshes witha gear 338 fast on a shaft 339 turning in a bearing of frame 331 and carrying a sprocket 349. This sprocket drives the chain 99 which extends from one side of the wrapper die to a sprocket 34I adjacent the other side, as shown in Fig. 1. To the chain 99, by means of pins 342 protruding therefrom is attached the carriag I99 which carries a stud 343 to which the holder of'the cutter rollers I6 is clamped. The arm I00 is provided with rollers 344 by which it is suspended from a track 345 aflixed to frame 331 and extending along the chain 99. The gear 349 is detachably fastened in driving engagement with gear 98 by means of a ball-end plunger 346 held by a spring-341 in a steel socket 348 inserted into the web of gear 98, this method of attachment constituting a safety devic against accidents to the operator, as the plunger 346 will be forced out of socket 348, thus stopping the chain, in case the rollers or their carrier arm encounter a major obstacle. This arrangement provides a desirable and valuable safety control for the Wrapper and binder servingoperator sinc it makes it impossible for them to be injured by the cutting mechanism due to the fact that driving engagement between the carriage I and rack 91 is broken whenever an operators hand or other obstruction placed in the'path engages with the moving carriage and stops it. Reciprocation of the carriage once being interrupted will. not be reinstated until gear 98 is rotated to seat pin 346 in socket 348.

A second roller IOI held against cam 82 by a lever I02 fulcrumed on a stud I03 in base 36 and tensioned by a spring I94 controls a rod I85 connected to a lever I96, Figures 1 and '1, which operates the plunger I91 of the wrapper paster 2|, in a manner similar to that shown in Patent No. 2,012,149, above mentioned.

A roller I98 held against the circumference of cam 83 by a spring I99 attached to a lever I III fulcrumed on shaft 42 actuates it to reciprocate other ends are connected with valves controlling suction ports in th housing 48 supporting the turret I I5, Figs. 1 and 2, carrying the wrapper dies I5.

In Fig. 18, a sectional elevation of the wrapperor binder forming die mechanism is shown. On turret I I5, carried by shaft II4 turnable in bearings 3| I of housing 48 and driven by bevel gear I23, are mounted two die holders 3 I2,'which may be of a type similar to those shown in my Reissue Patent No. 19,671, granted August 20, 1936, in which are slidable rods 3I3 supporting the transfer head I28. Plates 3I4 fastened todie holders 3I2 carry the die shells I5 and the cutter knives 3I5,'held thereon by clamps 3I9. The rods 3I3 have rollers 3I1 resting on a track 3I8 which raises the heads I28 above the cutter knives 3 I 5 in' the die-serving position and causes them to descend. below the knife surface in the cutting position. When arriving in the wrapper delivery position, an extension 3I9 of the studs of'rollers 3I1 engages with a pocket 329 at the end of rod I21, which by means of lever I25, cam ifollower I24 and cam 85 raises the head I28 with thecut Wrapper so that it is lifted into engagement with the suction head I1 of the wrapper carriers. Shortly after the head I28 has been raised to the position shown in Fig. 18, the suction therein is cut off and directed into conduit 334, which. feeds it to the leaf section carrier head I1 (Fig. 1) thereby effecting delivery of the wrapper or binder, as the case may be, from head I28.

The suction for hOldiIlg the wrapper on the die head I28 is supplied by a pipe 32I suitably connected to housing 48 from which ducts 322 and 323 lead to a disk valve 324 fixedly attached to housing 48. The inlet of duct 323 is controlled by a butterfly valve 325 held in the open position against a stop 326 by a spring 321 attached to a collar on the valve shaft and fastened to a stationary disk 328, the said valve being closed at timed intervals by a crank arm 329 engaging with a slot in the rod III attached to cam lever H6. In the dwell positions of the intermittently rotating turret H5, port-openings of valve 324 register with ducts 336 and 33I leading to the shell I and to the suction head I23 of each die, the rotation of turret I I5, in conjunction with the timed action of valve 325 producing the different suction conditions required in different positions. The arrangement of the ducts 322, and 323 and stationary valve 324 may be similar to that shown in my Reissue Patent No. 19,677 mentioned above.

The rod H2 attached to lever II I! operates a I butterfly valve 332 which normally closes the inlet of a duct 333 communicating by pipes 334 and 335 with the pedestal 52 of wrapper carrier I1. Thus, when the action of lever I I6, at the time of transfer of the cut wrapper, closes the duct 323 and thereby shuts off the suction in die head I28, it simultaneously opens valve 332 and thereby admits suction tothe carrier head I1. In Fig. 19 the positions of the valves 325 and 332 are shown on plate I28 in approaching its uppermost location. When that point in its travel is reached valve 325 is rotated to close duct 323, thereby shutting off the suction in said duct, While valve 332 is rocked to allow the suction to be diverted into pipe 334. Since a similar structural arrangement is provided for the binder dies and binder transfer, it need not be described further herein.

The shaft I I 4 of die turret II 5 is intermittently driven by an indexing member provided with a plurality of rollers H6 engaging with a track in cam 84 which is integral with cam 83. The rollers H6 are mounted on a disk H1 on a shaft I I8 supported in housing 48 and carrying a gear H3 meshing with a gear I29 on a shaft I2I on which is also mounted a bevel gear I22 meshing with a gear I23 on shaft H4. Since the turrets are moved through 180 during each indexing thereof two rollers I I6 are provided at diametrically opposite points on disk H1. The construction of the disk H1, rollers H6 and cam 84 may be similar to that shown in my Reissue Patent No. 19,677.

The cam 35 engages a follower I24 carried by a bell-crank lever I25 fulcrumed on shaft 42 and held in engagement by a spring I26, Fig. 2,. the lever I25 being pivoted to a rod I21 (Figure 18) operating the transfer head I28 of the dies I5.

The gear 89 on cam shaft M, Fig. 7, meshes with a gear I 29 on a shaft I30 supported in housing 41, the latter gear meshing through an intermediate gear II3 (Figure 2) with a gear I3I on the shaft I32 of the wrapping device I4, see Fig. 2. To shaft I30 is also afiixed a bevel gear I33 meshing with abevel gear I34 on a shaft I35 carrying a gear I36 and a cam 35L The latter is employed to drive the bunch turret I31, which is mounted on housing 41, when the machine is used in connection with a short filler bunch machine, as shown in Fig. 9. While it is not essential that all of the parts of the short filler bunch forming machine run in synchronism with the rolling mechanism, it is necessary that the turret I31 operate in synchronism therewith in order that shaped bunches may be properly fed in timed relation to the rolling elements.

With cam 35] engage the rollers 352 of an indexing device 353 thereby imparting an intermittent rotation to shaft 354, on which is mounted a pinion 355 meshing with a ring gear 356 attached to bunch turret I31 which is loosely mounted on shaft 351. The gear I36 on shaft I35 meshes with a gear 358 fixed on shaft 351, and thus imparts continuous rotation to the latter shaft which drives the operating member of the pocket cover of the turret. The details of the turret I31, its drive and cover operating member are similar in construction to that shown in my co-pending application, No. 21,723, filed May 16, 1935, now Patent No. 2,157,537 granted May 9, 1939.

Cam 86 in a face trackguides a follower I36ona lever I39 swinging on shaft 43 and actuating a rack I40 extending upwards into the pedestal I4 I, Fig. 1, and operating the cigar transfer 23, see also Figs. 11 and 12. controls a follower I42 carried by an arm I43 of a lever I44 to which is pivoted a rod I45 operating the valve lever I46 of flag blow-off 22, in a manner similar to that shown in said Wheeler Patent No. 2,215,490.

The track of cam 31, which is integral with cam 86, engages a roller I41 on a lever I43 fulcrumed on shaft 43, the free end of this lever being pivoted to a rack I49 which, like rack I45, extends into pedestal I4I but actuates the bunch transfer I I. The complete structural arrangement of the bunch end cigar transfer is shown in Figs. 11- to 17, and is described hereinafter.

On the bunch transfer I I is mounted a balance arm I50, Figs. 1 and 2, held by a spring I 5I in its up-position I53 in which, onthe swinging of the transfer along path I3 (Fig. 2), it engages the nose I52 of an arm I53 affixed to a vertical shaft I54 extending from pedestal I4I. In its up-position, the lowerend of the balance arm I56 rests on a plunger I55, Figs.3, 3a and 31), carrying a toggle joint I 56which is then in its down-position with transfer fingers I51 located apart for the entry of a cigar bunch B. In entering the fingers I51, the bunch B trips the toggle I55, thereby raising theplunger I55 andturning the balance arm I50 into its down-position in which it clears the nose I52 when the transfer arm II is moved through its prescribed arc.

When at any time the transfer fails to pick up a,bunch,the toggle I56 is not tripped, balance arm I50 remains in its up-position I56, and shaft I54 will be rotated through a given angle by the arm I53. On the lower end of shaft I54 is attached a switch I58 which is held. open by the shaft I54 when the arm I53 is in its normal undisturbed position. If, however, asstated above the shaft I54 is moved by the balance arm I56, switch I58 closes contact I59 which isconnected in series with a timing or limit switch I66, and with a solenoid I6I, the limit switch being closed by the raising of a spring-tensionedroller I62 through its engagement with a cam piece I63, attached to the-periphery of cam32. The soleq The periphery of cam noid I8I when energized at the proper moment by the co-action of switches I58 and I68, pulls a lever I64 pivoted on a stud in bracket I65 into the path of the lifter lever I25 actuating the rod I21 which operates the lifter head I28 and transfers the cut wrapper from the die I to the wrapper carrier II, thereby preventing the same from rising to effect such transfer.

Thus, there is provided an automatic inspecting mechanism which detects the presence or absence of bunches in the transfer device. By means of this device the feedof wrappers to the rolling or wrapping mechanism is so controlled that a wrapper'cannot be transferred from the cutting die for transfer to the wrapping station unless a bunch has indicated its presence in the bunch transfer member. Obviously, this makes possible an appreciable savings in the wrappers which are an expensive item in cigar manufacture, since it prevents the waste of the wrappers fed to the rolling mechanism whenever a bunch is not transferred thereto for association with the particular wrapper. This structure, therefore, adds much to the efficiency and practicality of the machine, and tends to'lower the cost of production of the cigars made thereon. a

The cam 82 carries a cam piece I83, the latter opening a limit switch I81, through enga'gement with a follower I68 carried by said switch and thereby stops the machine at the end of each,

long filler combination and the foot'pedalsare released, springs I69 connected thereto draw them upward against their respective stop screws I18 (Figure 2), thereby opening the switches 33 and 34. However, if both foot pedals are kept depressed, the machine willrun continuously.

A different switch arrangement obtains when the machine is operated as a short filler combi nation, see Fig. 80. Itmay happen that the bunch operative operating the bunch making machine falls behind for some reason and must stop the operation of the rolling machine, and

rotation ofturret I31 in order to catch up and fill the turret pockets, also, if for any reason she is subjected to danger and it isnecessary to stop the rollingmachine, this may be done at once by depressing the foot pedal which normally maintains switch 34 closed. The switch ar- =rangement in the case of the long filler combination is different from that just described because, as shown in Figure 18, in the long filler bunch forming combination all bunches are moved automatically from one unit to another. A dif-; ferent condition exists in the short filler combination, however, where each bunch is transferred manually from the bunch making mechanism to the mold turret on the wrapping unit thereby making a different method of control advisable. When switch 34' is opened the circuit is broken and the machine stops, regardless of the position of the limit switch 7 I81 which normally causes a cyclical stoppage of the machine.

On the free end of worm shaft 52 is mounted. a sprocket I1 I, Fig. 2, which by means of a chain I'I2 drives the sprocket I13 of a pump I14. The latter is mounted on a bracket-fastened to shaft 46, Fig. 2, and supplies compressed air to a reservoir I which is connected by pipes I16 to the hollow pedestal I" which carries the flag blowoif 22. Integral with the hub of sprocketI'II is a bevel gear I18 meshing with a bevel gearIIS on a shaft I88 supported in end frame 38, the end of shaft I88 being adapted to receive a hand 1ever I8I, Figs. 9 and 10, for cranking thema- ,after one of the overload relays I88 or I 81 has broken the circuit, restores its contact and when the on button is again depressed the motor is set into operation and restarts the machine. From the starting switch 38, an electric cable I88 leads to the motor 28 and a cable I89 runs to a connecting box I98 to which the hand switches 3| and 32 are connected by cables I9I and I92, respectively. From box I98, a .cable I93 runs to the foot switches 33 and 34 and limit switch I61, and a cable I94 runs to the solenoid I6I. From solenoid Nil, 9. cable I96 leads to the wrapper control switch.I58I59, a second cable I91 to the limit switch I68, and a third cable I98 to the jogging switch 35 which is shown in the running position. Fig. 8a shows the position of the switch 35 for stopping the machine, and Fig. 8b for jogging, the machine in the latter position of'the switch running for a short time aslong as the contact button I99 is depressed. 'A cable 288 connects the jogging switch 35 with the solenoid I5 which controls the expansion ring 69 actuat- -ing the main clutch 29 of the machine.

A cable I98 is tapped by a cable 28I leadingt a lamp 282 mounted in the substructure of the machineso as to illuminate certain operating .mechanism for making adjustments when the lamp switch 283 is closed, the housing of the wrapping device I4. being for this purpose pro- .vided'witha suitable aperturai As mentioned hereinabove,1the. cigar rolling stituted and be set in working order with the rolling machine, and conversely.

Due to the fact that thebunch and cigar transfer mechanism II and 23 respectively are mounted to operate in a single'pedestalMI located'on the table of the cigar rolling machine, there is no necessity for changing. and adjusting the bunch transfer structure except for the gripof the long filler machine, will occupy the same relation'withrespect to transfer arm II regardless of the combination of units used, whereby the chine is shown. The bunch forming machine mechanism may be of the type shown in British Patent No. 503,132, which discloses a hopper adapted to contain a bulk supply of tobacco which is fed intermittently therefrom to the bunch forming device. In this case, the continuously running inner drive shaft 55 of the rolling machine is coupled to the drive shaft 264 of the bunch machine by a coupling 295, the latter drive shaft by gears 22S driving a clutch 201 similar in construction to the clutch 29. The bunch forming machine is intermittently driven from shaft 204 through the clutch 201 under the control of foot pedal 362 at a much higher rate of speed than the rolling machine so that a sufficient number of bunches may be supplied to the pockets of turret I31. For example, if the output of bunches from the rolling apron 230 be set at, say, twenty-one per minute the rolling machine may be set to produce, say, twelve cigars per minute. In this manner the numerous pockets of the turret I31 are maintained substantially full. The speed is of course set so that the best possible output of the machine can be obtained. The clutch 291 is controlled by a solenoid 2G8 receiving its current by a cable 209 from a connecting box ZIB which through a cable 2 is wired to a socket 2 I2 of a switch box 2I3 on the table of the machine. Gear 224 on shaft 201a drives gear 55 on shaft 509 of the short filler bunch forming mechanism (Figure 9). Treadle 362 fulcrumed on a shaft 5! of the bunch forming mechanism is provided with a suitable extension 5B9 mounting a switch closing member 598 of any known type adapted to engage contacts 5I I and close a circuit through wires 209 whenever the treadle is depressed whereupon solenoid 208 is energized to cause clutch 201 to drive shaft 208 and the various driving mechanisms of the short filler bunch forming device (not shown). The box 2I3 receives current by a cable 2I4 from the connecting box I99 of the rolling machine and also has a socket 2I5 connected by a cable 2 IS with the heater 2I1 in the bunch turret I31, this heater being controlled by a switch 2I8 on box 2 I3. In Figure 3, the connections of box I90 with foot controls 33 and 34 by cable I93 is shown, which allows clutch 221 to be controlled by the foot pedals. A micro-switch 359 (Figure 8d) controls the operation of the rolling machine and thereby prevents injury to the operator feeding the bunch turret. This mechanism may be constructed to operate in a manner similar to that shown in copending application, Serial No. 195,528, filed March 12, 1938, by J. P. Durning, now Patent No. 2,275,423, granted March 10, 1942. This switch is manually reset to reinstitute the operation of the rolling machine.

A bevel gear 2I9 on the drive shaft of clutch 201 meshes with a gear 220 on a shaft 22I supported in the side frame of the bunch machine and serves to crank the sun gear of the clutch 201 manually by a handle 222. A pulley 223 on shaft 204 and a gear 224 on the shaft 291a of clutch 201 drives the various operating units of the short filler bunch rolling machine, which may be of the type shown and described in the above referred to co-pending Durning application, namely the feed hopper 225 with the rakes 22S and the delivery door 221, the charge-weighing scale 228, the charge cutter 229 and the rolling table 239 with the bunch receiving clamp 23I,

' from which the operator transfers the finished bunch to the turret I31, which may be of the type described in co-pending application No. 195,528, referred to above.

The short filler machine, above referred to and as shown in Fig. 9, may be equipped with a scrap drawer 232 into which lead pipes 233 and 234 from the rolling table and from a chute 235 at the bunch turret, respectively, the drawer 232 being connected by a pipe 236 with a pipe 231 rising from the suction outlet 238 of the rolling machine. The pipe 231 leads into the housing 48 of the turret II5 of the rolling machine and by a pipe 239 also connects with a duct in the pedestal 92 of the wrapper carrier from which a pipe 240 leads to the suction chamber'2-II of paster 2|. A chute 242 below the trimming end of re-roller 25 is connected by a pipe 243 with'the suction system, the end of pipe 243 passing through chamber 48 and entering part Way into suction pipe 231. The delivery position II of bunch transfer I I, and the receiving position 23' of cigar transfer 23 are shown in dotted lines.

In the long filler combination shown in Fig. 10 the clutch driven hollow shaft 52 of the rolling machine is connected by a coupling 244 to the drive shaft 245 of the bunch machine, so that all operating units of the latter are in synchronism with those of the former. The units shown of the long filler bunch machine are the filler feed 246, the filler cutter 241, the filler forwarding plunger 248, the charge cutter 249, the latter group operated by mechanism enclosed in a housing 250; the charge transfer 25 I, the rolling table 252, the binder die turret 253, the binder cutting rollers 254, the binder transfer 255, the binder carrier 256, the binder paster 251, the bunch softener 258, the bunch transfers 333 and 364 and locator mechanism 259, and the bunch shaper 259. All units of the bunch machine are controlled from the rolling end of the combination, the manual switch 32 and the foot lever 34 of the rolling machine being within easy reach of the operator serving the dies 26I of the binder turret 253. Near the latter, a chute 262 is provided in the table top of the bunch machine to quickly dispose of the scrap from the binder dies.

The construction of the bunch and cigar transfer, which carries the cigar bunches from the bunch machine to the wrapper applying device of the rolling machine, and, after wrapping transfers the cigar to the re-roller, is shown in Figs. 11 to 17.

The rack I 49, which is actuated by cam lever I48 on shaft 43 and guided by a flanged wheel 253 engages a gear 254 on a shaft 265 supported in pedestal I4I. The guide wheel 263 is mounted on an eccentric stud 266 thus permitting accurate adjustment of the tooth engagement. The shaft 265 passes through the hub of a bevel gear 251 which is held fast to pedestal I4! by a bolt 268. On shaft 265 is turnably mounted the flanged hub of the hollow arm I I in which is journaled a shaft 269 carrying at its ends bevel gears 219 and 21I. Shaft 265 has a crank arm 212 which is detachably connected to arm II by means of a spring-tensioned ball-top plunge 213 fitting into a steel socket 214 inserted into the hub-flange of arm II. The gear 210 at the inner end of shaft 269 meshes with the fixed gear 251, and the gear 21I at its outer end engages with a gear 215 on a horizontal shaft 216 journaled in arm II and carrying the bunch holder 211. The turning of the gear 210 as it rolls on the stationary gear 261 rotates the horizontal shaft 216 by an angle equal to that through which the arm II is moved by the crank 212, thus keeping the bunch holder 211 in its vertical position at all times and at any angle of arm II. Therefore, when a bunch or cigar is to be lifted or delivered, the grippers are always properly positioned for correct operation. the arm II has two adjustable stop screws 218 which engage alternately with a stop 219 in either position H of the transfer arm, corresponding to the spaced position B (Fig. 11) of the cigar bunch, in the bunch-machine turret and in the wrapping device, respectively. In case the stroke of rack I49 is made slightly greater than required for the correct adjustment of the screws 218, the plunger 2'I3 leaves the socket 214 at the end of each stroke and snaps back at the beginning of the next, and no damage is done to the mechanism.

The rack I which is actuated by link 283 on cam lever I39 is kept in lateral alignment by a guide block 28I fitted into pedestal I41 and fastened to base I2 and held in tooth engagement with a gear 282 on a shaft 283 by a flanged wheel 284 on an eccentric stud 285. The shaft 283 passes through the hub of a bevel gear 2523, held stationary in pedestal MI by a screw 281, and

carries the transfer arm 23, the stop screws 288 of which engage with a stop 289 at its end position, corresponding to the positions C (Fig. 12) of the cigar in the wrapping device and in the re-roller, respectively. The arm 23 has the shafts 290 and 25 with the bevel gears 29 2, 293 and 294, the horizontal shaft 2! on a cross stud 295 loose in its fork end 296 carrying the cigar holder jaw 29'! which is held in tension by a spring 293 pressing against pins 299 and 300, and is opened and closed against a stationary cigar holder plate 20| attached to fork 296 by a pin 302 ina collar 303 fast on stud 295, the said pin being controlled by a cam piece 304 attached to arm 23.

When the transfer is used in the short filler bunch combination shown in Fig. 9, the cigar bunch B is turned through a right angle while being transferred from the bunch machine to the rolling machine. The horizontal shaft 215 of the transfer arm H carries a bevel gear 305, Figs. 16 and 17, fixed tosaid shaft and meshing with a gear 306 on the holder 21'! which in this case is loose on a vertical core 301 clamped to the end of shaft 216. The tooth ratio of gears 305 and 306 is so chosen that gear 303 moves in excess of one-quarter revolution with the spring overthrow stops as gear 305 turns through an are equal to that between the extreme position BB of transfer arm H, i. e., thearch indicated by arrow I3 in Fig. 11.

The shaft I54 of arm I53 is held in position through friction produced by a spring 308 pressing on the clamp .309 carrying the switch I53 which when turned by arm I53, connects the insulated terminals on contact piece I59. The nose I52 is held against a projection on arm I53 by a spring 3I0, permitting the balance arm I to continue its forward motion by turning the nose out of the way after the switch I59. has contacted, and to re-engage the same on its return motion so as to turn arm I53 back into neutral position.

It is to be noted that the transfer mechanism for conveying bunches and cigars to and from the various operating stations of the machine are substantially entirely enclosed and are extremely simple in construction and operation. This makes possible a more efficient transfer than known heretofore, and insures greater wearing qualities for the parts making up their organization, since dirt, dust and possible abrasives, which are'often present in tobacco, cannot get into'the working parts of the transfer. Furthermore, the safety of an operator is greatly increasedidue to the enclosing of all parts so that it is impossible for her to come into contact with said parts. Also, the cleaning of this mechanismcan readily be effected without danger of clogging any of the parts since it merely requires awipingcf plain, rounded exterior surfaces.
